The Knob Tool is an ActiveX control. As such, a Knob Tool object has an ActiveX page on the Property Sheet. Many of these properties are the object’s formatting properties. Values for the ActiveX Properties can be set directly on the ActiveX page or in the OCX Properties dialog box, which is accessed by clicking the (OCXProperties) property.
